/ p Application filed August 17, 1905. Serial No. 274,641.

To all whom 'it may concem:

Be it known that I, HERMAN HoLLnRrrH, a citizen of the UnitedSta-tes, and a resident of Garrett Park, Montgomery county, Maryland, have invented certain new and useful Improvements/in Apparatus for Use in Tabulatin Systems, of which the followis a fuliclear, and exact description, reference being had to the accompanying drawings, forming part of this specification. H

The object of this invention is to provide means for operating registering and other apparatus used in the Hollerith tabulating system in which is employed arecord card having -indexpoints, preferably punched holes, which are located on each particular record card in accordance with the data which that card represents. The system, of which these record cards form a distinguishing characteristic, comprises apparatus for registering the items constituting the record formed on each record card and totalizing or integrating the items of any desired number of the record; apparatus for indicating, without totalizing, the record on each card; apparatus for sorting or classifying the record cards into groups; apparatus for veri ''ing the accuracy of the record on each card by rejecting or separately grouping such records as may contain inconsistent or incongruous items and other apparatus for performing analogousapr incidental op erations in the complete tabulation of the records.

The operation of the apparatus above referred to is all variably controlled by the record cards and the result of each operation thereof depends on the particular record on the card which is then in control of the apparatus, and I have therefore hereinafter in to such apparatus, whether employed or integrating, sorting or verifying the records, for indicating the items of a record or for the other purposes referred to. described it generically as apparatus adapted'to be operated according to the lo cation of the index points on the record card.

My invention comprises the use of a rec- 0rd such as described, and in which the index-point positions are arranged in column, a record-actuated (lCYlCE, such, for example,

as a pair of electrical contacts, common to all the index-point positions of a column, which are put in action by the index-point, an operating circuit initially controlled by the record-actuated device or contacts, and means for holding such circuit under control for a variable period during each cycle of the machine, the duration of which is determined by the location of the index-point in its column. Electricity is the agent preferably'employed for effecting the control or operation of the apparatus but it is not my intention to restrict my invention to the employment of that particular operating or controlling agent since other equivalent means may be employed instead of an electric circuitor circuits and electrically operated devices hereinafter described; but I;

consider electricity to be the most advantageous agent and have therefore selected,'

for the purpose of description, an electrically operated apparatus, and in this connection it is to be understood that where electricity is employedas an actuating or controlling agent the apparatus may be arranged for operation either on open or closed circuits.

My invention also comprises an apparatus of the character referred to, actuated by means ot a record-card with index-point posltions arranged in column, having a recordactuated'device common to the index-point ,7 PGSItIOIIS of a column, registering, indicating or sorting devices and an electro-magnet for controlllngtheir operation which 1s held under control for a variable period during duration of which is determined by'the location of the index-point on the record, which is moved relatively to the recordactuated device.

25 more columns of figures comprising the nine and contact mechanism and In the accompanying drawings, Figure 1 is adiagrammatic View, (shown partially in perspective), of my invention arranged to operate registering devices; Fig. 2 is a similar View showing my invention arranged for sorting or grouping the records; Fig. 3 is a partial diagram showing indicating devices; Fig. 4 1s a similar diagram showing a modification of the arrangement illustrated' in Fig. 1; Fig. 5 is a diagrammatic view showing a modification of the recordactuated contacts and circuit; Fig. 6 is a view of a record card on a larger scale; Fig. 7 is a detail end view of the card feeding Fig. 8 is a plan view thereof.

Similar reference characters are employed to designate like parts in all the views.

In the form of record-card which I havethe purpose of illustrating and selected for describing my invention, but without intendingto limit my invention thereto, the

' value or of amount Which does not exceed index-point positions, as shown in Fig. 6 are denoted by printed figures arranged in groups, each group consisting of one or digits and a cipher substantially as shown in my U. S. Letters Patent No. 777,209, with the cipher, (except in Fig. 5), at the top of each column in horizontal alinement and the digits following in order down each column to the figure 9. To secure brevity in this description I have shown only three columns of index-point positions, it being assumed that each card contains a record of one thousand, but this theoretical form' of record will enable the principle of operation I of my present invention to'be readily understood. In Fig. 1 I have illustrated my invention in a simple form adapted to integrate these records and to operate electric- Referring for the present to Fig. 1, a suflicient number of the records 1 are placed on ed c, with the cipher at the top, upon a suit ab e platform 2 and are fed one by one to the action of the record-actuated contacts, to be presently described, by a reciprocatlng ceoss head 3,'rotatin drum '4, feed rollers 5 and, if desired, suppIemental feed rollers 6.

ma 'be substantiall imilar to that shown and described in my S. Letters Patent No. 685,608, dated October 29th, 1891, further description thereof in this specification is unnecessary except to state that the cross head 3 is reciprocated by a connecting rod .8 actuated by the crank;

disk 9 which is constantly driven ins chronism with the feed rollers, rotating Y drum 4 and other parts of the apparatus hereinafter referred to, by a suitab e motor 12. The drum 4, as shown in-Fig. 1, is made of conducting material and forms one termi- 119.1 of an'electric circuit, current being conhole is veyed thereto by the conducting brush 13, I

so that their flexible ends, which are normally in contact therewith, are separated therefrom when a card is fed down between them and the drum. Each of the conducting brushes, (15, 16, 17), forms, with the conducting drum 4, a pair of electrical contacts which are actuated, or permitted to come together. and move apart, by the record, and I therefore, for the sake of brevity, refer to each pair of'these contacts as record-actuated contacts. The right hand column of index-point positions on the cards represents units, the middle columntens and the left hand column hundreds and to transfer an item, say .the number 508 to the card, a unched in the left hand column at the position denoted by the figure 5; in the middle column at the position denoted by the cipher and in the right hand column at the position denoted by the figure 8. \Vhen the card is fed down between the brushes and drum the index-point positions of each column, each of which represents a different characteristic or amount, are presented successively to the brushes or record-actuated devices, and when the punched hole in a column registers with the brush for that column, the brush will contact with the drum and an electrical contact will be established momentarily. The time at which the recordactuated devices are thus actuated to establish such contact, depends upon the locatlon of the punched hole constituting the indexpoint, and in order that the circuit shall be established initially only through these contacts I provide a contact which will hold the circuit open at another pomt at all times when no card is'between the drum and the brushes, as for instance during the period that ela ses between the passage of successive car s. This contact is preferably, but not necessarily, actuated by the card itself and as shown it consists of the opposed springcontact-arms 20and 21 tending to close the circuit. A spring-depressed rock arm 22' engages the contact arm 21 and is secured to the rock shaft 23, to which is also secured an arm 24, carrying the roller 25. The roller 25, when no card is in position between the brushes 15, 16 and 17 and the drum 4, 1s held lightly in the groove 26 on the drum by the spring 27, and the arm 22 will hold the contacts 20 and 21 separated, but when a card is fed down it will pass between the drum 4 and the roller '25 forcing the latter but of,

the cove 26, raising the arm 22 andpermittlng the contacts 20 and 21 to come together to close the circuit,

Still referring to the particular form of app atus-illustrated in Fig. 1, each of the The magnets 35, 36 and 37, which I may designatev as control magnets to distinguish them from the relay magnets, are connected to the return wire through the contacts 40. The contacts 10 are arranged to be separated to break the circuit simultaneously through all the magnets, by a constantly revolving cam 41, at the instant the advancing movement of the card brings the index-point positions, denoted by the ciphers, under the brushes 15, 16 and 17. Each of the contacts 45, d6 and 47 is connected in series with one of the relay magnets and with its connected control magnet and each of the armatures 48, 49 and 50 of the relay magnets is separately connected to the opposite side of the line, so that when "a circuit is established through any of the relay and control magnets by the card-actuated contacts, which are closed only momentarily, the armature of the relay magnet will be attracted to its contact, closing a circuit at that point which will include the coils of the relay and control magnets and such circuit will be held closed. after the record-actuated contacts are separated, until it is broken by the cam e20 at the instant the zero index-point positions on the advancing record are under the brushes.

The specific devices adapted to be operated according to the location of the index-points on the record card which I have illustrated in Fig. 1 comprise a register wheel or member and suitable driving means therefor, such asa clutch disk. Three such register wheels, 56 and 57 are illustrated in Fig. 1 which is intended to illustrate a typical ,form of registering apparatus; buttheirnumber may of course, be varied, as desired. Any desired form of registering apparatus embodying directly actuated registering members with means for carrying or transferring from one meniber to that of the next higher order, accumulating members and zero resetting devices may be employed, and I have therefore not considered it necessary to illustrate or describe the same in detail since their construction and operation are well understood by those skilled in the art.

In the registering apparatus, 51 represents the thousands wheel which is an accumulating wheel actuated only by the transfer mechanism, 55 indicates the hundreds wheel,

, 56 the tens wheel, and 57 the units wheel, and

the wheels are provided with a suitable sight opeiling, (indicated by dotted lines) through which only one number of each wheel is exhibited. Each wheel is mounted loosely on the shaft 60 which is constantly driven at a uniform speed by the pulley 61, suitably connected to the motor 12, in synchronism with the moving card. The wheels are suitably supported so that the turning movement of the shaft 60 will not actuate the wheels until they are brought into positive connection therewith. Each of said wheels is pro- 73 vided with a series of peripheral numbers from O to 9, and in the form of apparatus illustrated this connection of the wheels with the shaft 60 is effected by means of a clutch, comprising a series of clutch teeth, one for each figure, on the wheels, and cooperating clutch members or disks 62, 63 and (3 1, splined on the shaft 60 so that they will slide on the shaft and turn therewith. These clutch members 6264 rotate constantly in one direction during the operation of the machine, thus avoiding any reversal of movement and permitting the operation of the apparatus at high speeds and without objectionable vibration.- ,Each clutch disk is provided with a clutch tooth which will engage a clutch tooth on its registering wheel when it is moved toward the wheel, locking the wheel and disk together so that the wheel 'will turn with the disk. j" The spring-retracted armatures 65, 66 and (37 of the control magnets are in the form of bell cranks and the depending arm of each bell crank is suitably connected to the hub of one of the clutch disks ()2, '63 and (i-l. lVhen any one of the control magnets is energized its armature will be attracted toward the magnet and the movement of the armature will carry the clutch disk connected therewith into locking engagement with its registering wheel. This engagement will be established by the closing of the circuit by the record-actuated contacts and will be maintained, .after'the record-actuated contacts are separated, by the circuit established through the relay contact until the circuit is broken at the contacts 40 by the cam 41. The shaft 60 is arranged to make one complete revolution while the index-point positions of a card pass under the brushes 15, 16 and 17. As will be understood the form and arrangement of the wheel-engaging devices or clutches are susceptible of modification, and I employ the term clutches in a broad sense as descriptive of any suitable connecting mechanism.

The operation of the apparatus illustrated in Fig. 1 is as follows: The punched cards being properly placed on the platform 2, the motor 12 is started and the'cards are fed down so aslto ,pass between the drum 4. 120

and the brushes 15, 16 and 17. At the inpoint 8 in the units column reaches the brush 17 when the latter will contact with the drum through the punched hole, closing the circuit through the magnets 27 and 37 and throwing the revolving clutch disk 64 into engagement withthe register wheel 57. The control of the register wheel by the magnet 37 thus established through the card contac'tsis maintained, notwithstanding the momentary duration of the contact between the brush and the drum through the moving hole on the card, by the simultaneously established circuit, formed by the contacting of the relay armature 50 with the contact 47, through the coils of the magnets 27 and 37,-the contacts lO to the battery and back to the relay armature 50. When the 5 index-pointin the hundreds column reaches its brush 15, the clutch disk 62 will be similarly actuated to impart the motion of the shaft -60 to the reglster wheel 55. The record un 'derconsideration will not close a circuit through the control magnet 36, because the cipher is "punched in this column, and the circuit will be broken at the contacts 40, by the cam 41 when the cipher or zero index-point positions reach the brushes, and therefore the only movement imparted to the register wheel 56 will be that due to the transfer or carry ing mechanism. When the circuit is broken at the contacts 40 the armatures 65 and 67 are released and the clutch disks 62 and 64 are drawn out of engagement with the regis:

/ their movement.

tering wheels, which stop at this point in To each register wheel has been imparted a movement which corresponds with, and is determined by, the location of its index-point on the record card. *Thus the wheel 57 will be rotated eighttenths of one revolution or while 8 of the '10 index-point positions of the column pass under the brush, while the wheel willbe rotated five-tenths of one revolution or While five index-point positions are passin under the brush, so that 8 will be added to the units whe"el,-nothing to the tens wheel, except by the transfer mechanism, and 5 to the hundreds wheel. As the record passes from under the brushes it is deposited in .a suitable receptacle, another record is presented and the action is repeated.

The form ofiapparatus embodying my invention which I have illustrated in F ig. 2 does not differ inits principle of operation from the apparatus hereinbefore described. The cardfeeding mechanism and card contacts are substantially alike in both forms of apparatus and require no further description. The devices adapted to be operated according to the location of the'indexpoints comprisev a. plurality of movable guides for'delivering or controlling the delivery of the record cards to different points so that. the records are sorted or grouped accordingto their index-points. Any scheme of sortingmay be employed which is desirable in handling the records either be-- fore or after tabulation. The'apparatus as shown is intended to sort the cards according to the location of the index-point inthe hundreds column, the cards on which the item recorded is less than one hundred being delivered in one group, those onwhich the item between ninety-nine and two hundred being delivered in another group and so on. I have also illustrated in Fig. 2 a

'the control of said devices in which the relay magnet is dispensed with and the 0011-. trol .of' the control magnet 7 0 is maintained by means of a contact 71-actuated by the movement of the armature 72 to engage with a contact 73 to hold the circuit through the magnet closed after the separation of the card contacts. The sorting guides 75 are mounted directly below the card-actuated contacts and are so constructed that the ends of the guides, whichaare held apart by the separators 77, may be reciprocated across the path of the cards. The guides are movable separately with relation to each other but are I yieldingly held to move in unison by springs The upper ends of the guides may be pivoted or they may be made of flexiblehaaterial to permit the requisite reciprocating movement. The left hand guide of the series rests against a rock arm 79 which is thigaged by a rotating cam 81) on the shaft 81 driven by the motor .12 and so arranged as to make one complete revolution for each card assing between the card contacts. Asv a card reaches the brush 18, (only one brush being employed in this modification), the

cam will be in the opposit position to that shown, with its longest radius to the rightof the shaft and the guides will all be held to the right of the path of the descending cards and against the rock arm 79 by the springs 78. pivoted to swing freely soas to follow the surface of the cam 'under the action of the springs. As the card descends the cam 80, which is arranged to revolve synchronously, permits the sprin s to draw the guides across thepath of t hecard so that when the 9 index-point position of the card is under the brush the first guide, (from theleft), will be just under the latch 84: whichforms an extension of the armature 72 pivoted at 85, and when the zero index-point posiing that none of the intermediate "points are punched), the tenth guide, \from the left), will be under the latch 84:, t e intermediate positions of the guides and card correspondmg at all times. If a'punched record'card e fed between the card contacts, as for ex-' modification in the means for maintaining 78 one of which is secured toeach guide and which tend to move the guides to the left.

The rock arm 79 is tion of the card reaches the brush, (assumwill traverse the index-point positions of the left hand column and when the 5 indexpoint position, (which has been punched),

reaches the brush, the fifth guide, (from the left), will be approximately under the latch 84. At this instant the circuit will be closed by the brush 18 through the coils of the magnet 70 attracting the armature and carrying the latch 81 down into the space between the fifth and sixth guides, holding back or arresting the movement of all the guides on the right while the fifth guide and all on the left of it will continue their movement. This separates the fifth andsixth guides sufficiently to permit the card to enter the space freely and by the guides the card is conducted to a suitable receptacle in which allcards similarly punched in the hundreds column will be deposited.

The cam 80 is of course, to be given the proper form to actuate the guides to receive the proper card, such form depending upon the distance between successive cards and the distance between the operative position of the cards and the tops of the guides. \Vhen the armature 72 is attractedtoward the magnet- 7 O the contact 71 carried thereby will engage the contact 73 and close a circuit through the battery, contacts 40, magnet 70 and contact 71, thus holding the guides separated until after the zero point positions on the index cards pass the brush, when the cam 41 will break the circuit, releasingthe armature and carrying the latch 84 out of engagement with the guideswhich will all be carried back to their initial positionby the cam 80, readyfor another operation. Any number of sorting guides up to the maximum number of controlling indexpoint positions on the cards may be employed; for instance if it be desired to separate the cards into two groups only two guides or a deflector for guiding the cards into either of two receptacles would be required.

In Fig. 3 I have illustrated a modification of my invention employing substantially the same means for maintaining the control of the control magnets as is shown in Fig. 2. In this modification each of the devices adapted to be operated according to the location of the index-point on the record cards comprises an indicating wheel and driving means therefor, by which the item or record on a card is simply indicated and which is then automatically reset at zero. The indicating wheels 90, of which three are shown, bear peripheral figures or other characters corresponding to the index-point positions on the card. As shown these characters may consist of the figures from 0 to 9.- A notch 91 is formed on each wheel for each character and the wheels are loosely mounted on brushes,

a shaft which is given one complete revolution for each card. The wheels are secured to the shaft 92 by a spring 93 which is secured at one end to the shaft and at the other end to the wheel so that, unless restrained, each wheel turns with the shaft, while if the wheel be held against movement the shaft will turn independently of the wheel and when-the wheel is released it will return to its initial or zero position. \Vhen the circuit through any of the magnets 95 is closed by the card contact, its armature will be at,-

I tracted to the magnet, carrying the detent 96 on the arm 97 secured to the armature, into one of the notches on the wheel and hold the wheel in position to show through the sight openingthat character on the wheel which corresponds to the index-point by which the circuit was closed. The magnet is maintained under control, with thewheel in its arrested position, by a circuit established by the contacts 98 until the zero index-point positions of the record have passed the contact of which three are employed as shown in Fig. 1. The circuit is then broken by the cam 41 and the wheels are set to zero position by the spring 93, which has been placed under tension by the movement of the shaft 92 after the locking of the wheelby the detent.

In Fig. at is illustrated a modification of Fig. 1 in which the relay magnets 25, 26 and 27 are dispensed with and the contact for closing the circuit, to maintain the control of the control magnet, is carried by the armature of the latter.

Although I prefer to employ electric circuits for the purpose of operating and controlling the devices adapted to be actuated 'accordingto the location of the index-points on the record card because many obvious advantages are secured thereby,I do not intend to exclude the use of equivalent operating or controlling means or circuits, nor to restrict the circuit or circuits to circuits which are closed to effect the" operation of the devices, since it is obvious that the operating circuit or circuits may be held under control while open or closed; nor is it essential, although I deem it desirable, that where a circuit is controlled by the record card, it should be actually closed through the card even where the operating or controlling circuit are electrio circuits, and as indicating how widely the details of the circuits, connections and operating means maybe modified without departing from the spirit of my invention I have illustrated in Fig. 5 a possible modification of the apparatus illustrated in Fig. 4, in which the cont-act for establishing a circuit to maintain the control ofthe devices to site end a contact 102, is mounted ,on the pivot 103, adjacent to the rotating drum 104.

I have shown only one lever but it will be circumferential? grooves 105, one for each column of index-point positions, and the spring, 106 tends to hold the point 101 in the corresponding groove on the drum with the contacts 102 and 107 separated. When a punched card is fed between the point 101 and the drum 104 it will swing the lever 100 to close the contacts 102 and 107, as shown, until the hole in the card reaches the point 101 when the latter'will enter the groove 105 through the hole, swinging the lever 100 sufficiently to open the contacts 102 and 107 momentarily until the advancing card forces the point out of the groove and closes the contacts. In this modification the cards are fed so that the index-points will pass under the point 101 in the opposite order from that heretofore described, that is to say, the posi-- tion of the cards or their feeding movement 7 is reversed so that the zero position will pass under. the point 101 first and the 9 position last.

A revolving cam 108 which'operates in synchronism with the card feeding means is arranged to move the armature 109 of the a magnet 110 into engagement with the con tact 111 at the instant the zero position of such card reaches the position 101. This movement of the armature causes the clutch disk 114 on the constantly rotating shaft 115 to engage the register wheel 116 and rotate the latter. having been closed by the advancing card just before the cam 108 moves the armature 109,.this movement of the armature completes the circuit through the magnet and the circuit is maintained bythe magnet after the cam moves out of engagement with the armature until the magnet circuit is broken at the contacts 102 and 107 and the armature released by the movement of the lever 100 when the point 101 enters the hole in the card. When the circuit is thus broken the spring 117 draws the clutch disk out of engagementwith the latter and the movement of the latter is arrested.
